Default CHE trunnion upgrade kit

I figured since my car was down I might as well do this now before I had a possible needle bearing failure. Each rocker has 66 needle bearings in it that I'm glad I got to remove before they got out. The trunnion kit is a bushing that is machined with oil grooves as are the rocker shafts. Easy to install with no special tools needed besides a c clip tool.

I had this done a couple years ago.
one of the needle bearings fell out once removed from the car

the "washer" like ring on the bolt head stated to work it's way up the bolt too... weird, should have taken a picture of it at the time.

I wondered how the sleeve bearing version of the trunion upgrade worked out for people. Seems like a fairly robust design, though I thought the trunion itself was only lubricated by "drip" oiling and not under pressure necessarily. Might be concerned with longevity of this design, but I'm sure someone has tested it.

I opted for the Comp Cams version with the encapsulated needle bearings on the last car I put together. I hope that these work just as well!

A lot of people who did the upgrades said it made the motor a lot quieter, which is an added bonus. I'll be able to verify that after I get my clutch put in, asshole took forever to ship it.

The motor is ALOT quieter, it got rid of the sewing machine sound of the valvetrain

I thought these are causing problems in the ls? What engine are these going in?

The only thing I heard about was an issue with the wear on the Comp sets
